UNITED STATES FRANCIS L. PERRY, OF CANANDAIGUA, NEW YORK.

IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 119,786, dated October10, 1871 To all whom it may concern:

Be it known that I, FRANCIS L.- PERRY, of Canandaigua, Ontario county,in the State of New York, have invented certain new and usefulImprovements in Cultivators, and I hereby declare the following to be afull and exact dcscription thereof, reference being had to theaccompanying drawing' forming part of this speciiication.

The nature or essence of my invention consists in the particularconstruction and arrangement of devices forming the improved cultivatordescribed in the following specification and represented in theaccompanying drawing.

In the drawing, Figure lis a perspective view of a cultivator with myimprovements. Fig. 2 is a tooth with a triangular point attached. Fig. 3shows a point with one end chisel-shaped and the other pointed. Fig. 4shows a tooth without a point.

In the accompanying drawing, A is the center-piece or beam of the frame,provided with a vibrating clevis, B, carrying the gauge-wheel C. Thisclevis is arranged to vibrate on a pin in the beam A, and it has aperforated segment, D, for the pin E, which also passes through thebeam, and may be placed in the different holes in the segment to adjustthe wheel C and graduate the working depth of the cultivator. The pin Ehas the latch F riveted to the end, so that when it is straight with thepin the pin may be drawn out and put back again, when the latch falls toa right angle and holds the pin in. The central tooth G is fastened inthe beam A by the nut Gl on the top of the beam, and carries thetriangular point or share G2, which is fastened to the tooth by a screwin the center and prevented from turning by a pin in the tooth or shankG; and the share or blade is provided with three holes, so that when onepoint is worn it may be turned to bring a new point forward. The sidebars H H are beveled at different angles at their opposite ends, so thatthey may be reversed when desired to make a narrow cultivator, and theteeth reversed in the bars. These bars are fastened to the beam by abolt, and are connected to the beam and to each other by the stand I, towhich they are respectively fastened by bolts; and the arms of the standI support and brace the handles J J, which have their fore ends fastenedto the beam A and are connected by the bar J f, as shown in the drawing.The teeth K are fastened in the side bars H H by screw-nuts, and areprovided with reversible points K1 fastened with a screw to the tooth orstock, and may bc used either chisel or pointed end ibrward, as may bepreferred. There are two recesses in the tooth to receive two lugs onthe point, which lugs K2 are made by heating the point and laying` itover a hole and driving a punch against the plate, so as to push some ofthe steel of the plate into the hole below and form a teat or lug on theplate to iit the recess in the tooth. I make some wide stands, L, andfasten them to the rear ends of the bars H by bolt and nuts, to carrythe wide shares or scrapers L1, which are fastened to the stands L bytwo bolts; and I make two holes for the upper bolt in the stand or inthe scraper, or in both, so as to tip the scraper and make the outercorner highest when it is desirable to hill the standing crop and lowestwhen it is desirable to throw the weeds and earth toward the middle ofthe row or from the crops. I fasten the bars N N by bolts to the rearends of the beam A and side bars H H, to form outriggers to carry theteeth P P1 P2, which may be made straight, as P, Fig. l, or with a coilin them, as shown at P1, or bent and with a coil, as at P2. These teethare fastened high or low in the bars N to adjust them to the servicethey are intended to perform. The object and purpose of these teeth inthe outriggers is to remove weeds from the hills and rows )f the cropsculti-A i A vated by this instrument. The share or scraper L1 has bothits longest edges curved, as shown in the end view L2, so that it may beused either end forward or either side up.

I claiml. Beveling the ends of the side bars H H at different angles andarranging them to be reversed to make the cultivator wide or narrow,substantially as described.

2. The outriggers N N attached to the cultivator, substantially asdescribed, and provided with rigid or spring-teeth made of round or ovalwire, for purpose'set forth.
